ISC2 Certified in Cybersecurity (CC)Network SecurityEasy
A company is implementing a new security policy that requires all remote employees to securely access the corporate network as if they were physically present in the office. They need a solution that encrypts all traffic and provides a secure tunnel over the public internet. Which technology should they choose?
- ASMTP
- BHTTP/S
- CVPN
- DDNS
Show answer & explanationAnswer & explanation
Correct answer: C. VPN
A Virtual Private Network (VPN) creates a secure, encrypted tunnel over a public network (like the internet), allowing remote users to access internal resources as if they were directly connected to the corporate network.
Why the other options are wrong
- A. SMTP is for sending email; it doesn't provide secure network access.
- B. HTTP/S is for secure web browsing, not for full network access.
- D. DNS translates domain names to IP addresses; it doesn't provide secure network access.
Virtual Private Network (VPN)
A technology that creates a secure, encrypted connection (tunnel) over a less secure network, such as the internet, allowing users to access private network resources remotely.
- Encrypts network traffic.
- Creates a secure tunnel.
- Enables remote access to private networks.
- Uses public internet infrastructure.
Memory trick: VPN is like a secret, private road for your data on the public internet highway.
